DETACHABLE HINGE.

Specification of Letters Patent.

Patented May 14, 1907.

Application filed December 18, 1906. Serial No. 348.463.

To all whom it may concern.-

Be it known that I, CARL J. ToLNEs, a citizen of the United States, residing at Mapleb ay, in the county of Polk, State of Minnesota, have invented certain new and useful Improvements in Detachable Hinges; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention has relation to hinges for screen and storm doors, windows, and in fact hinges designed to be applied to any device or devices that it may be desirable to remove from time to time.

It is the object of-my invention to provide a removable hinge that shall be eflicient as a hinge in the highest degree; that may be readily removable and replaceable with the object with which it is connected, and that may be low incost of construction and easy of manufacture, in order that it may be brought into common use. p

The nature of the invention is ascertainable from the means portrayed in the annexed drawings, forming a part of this specification, in view of which the invention will first be described with respect to its construction and mode of operation and use.

Of the said drawingsFigure 1 is a front elevation of the detachable part of my invention, showing it as applied to what may be considered a screen or storm door or similar object. Fig. 2 is a similar view of the part of the hinge that is fixed to the door casing. Fig. 3 is a longitudinal vertical section in the plane 1 1, Fig. 3. Fig. 4 is a transverse section in the plane 4 4, Fig. 3. view of the complete device attached to a door and its casing.

Similar numerals of reference designate similar parts or features, as the case may be, wherever they occur.

In the drawings 10 and 11 designate leaves of what may be considered as an ordinary butt or hinge, excepting as is hereinafter explained.

12 are the knuckles and 13 the pintle pivotally connecting the same.

Instead of the leaf 11 being provided with holes 14, as is the leaf 10, for the reception of fastening screws, it is made devoid of holes of that kind and is provided with a slot, 15, extending centrally from its lower edge Fig. 5 is a front up nearly two-thirds of the way into its body.

16 designates the permanent member of the device, which is made coextensive as to height with the member 11, but somewhat wider, and provided at its outer vertical edge with holes 14 for the reception of screws to fasten it to the casing 17 of a door, 18. The member 16 is composed of an integral section of material bent upon itself to form overlying plates which, for the greater part of their area are spaced away from one another, a bar 19 being fixedly held between the spaced portions of such plates, and being of size and shape to conform to the slot 15 in the leaf 11, said bar being designed to enter said slot when the leaf 11 is introduced into the space between the plates of the member 16, and moved downwardly in such space.

By the operation described above the door 18 will be hung upon its hinges. When it is desired to take the door off or remove the same, it will be simply raised up, carrying with it the hinge members 10 and 11 and leaving the member 16 secured to the door casing ready for employment when it may be again proposed to hang the door.

The member 16 is fiat on its outer face having no projections anywhere to be in the way of catching upon any object moved about in proximity thereto, and when the part 11 is connected with it, as when the door is hung, the two connected members become practically one in strength and function.

In addition to the handiness and efliciency of the invention, its simplicity of construction is a feature of importance.

What is claimed is A removable hinge comprising two leaves and their pivot connection, one of the leaves being provided with a slot extending upward from its bottom edge, and a member adapted to be fixedly connected with an object, the latter member being composed of doubled leaves, a bar, adapted to fit in the said slot being secured between the doubled leaves to receive the slotted leaf between them with i the bar engaging the slot.

In testimony whereof, I aflix my signature, in presence of two witnesses.

CARL J. TOLNES.
